There is way more people like that. I would asume that like 2 out 5 maybe 10 players i face on higher ranks - lets say demigod and up is using macros. There is just no way that you can be on point EVERY single time in a game and with so many characters on top of that. Played him several times, sometimes won, sometimes lost but the one constant thing was always that he is 100% on OS, wake ups, combos.
It was the same story with MK X and him (he played bojutsu mostly), always perfect on everything. Private matches and private tournaments is the way. Also i always laugh when someone is talking about good players (especialy) on PC and they throw The Greates Kahn in that mix. Nothing really changed since MK X.
